Precision Billet Turbos

[donut_kng]

If you looking for a 3076R equivalent then go the 0.63/ 5558 which is what I did from research and Unigroup's advice, if you looking for bigger, then consider the 6XXX series...

I spent a heap of time comparing numbers on this also.

For memory when I looked at this (I dont have the numbers on me) the 6262/6266 are pretty much similar to a GT3540 and the Precision 6466 is somewhere between a GT3540 and a TO4Z# .

Obviously how these would drive will also vary based on the rear housing size/ split pulse or not etc.

All the T3/T4 ones are, AFAIK.

If you got one of their garret copy items it would have a water cooled core (IE the T28/GT30 variant stuff).

I always assumed bb chra had oil and water cooling.

I guess no one has had many issues with it though.

What did you guys do with the water lines? Just link the feed to the return with a braided line or something?

Looks like what they did with mine- connect the two up with a hose or something

Any seen a compressor map for a PT5858, 5862 or 6262 or where to find them i did email precision but no response .

Tune all done, ran out of pump (fuel) top end so we stopped there but I'm fairly happy with how it went... May chuck another pump in and see how it goes but I'm happy for now

PTE 6262 on stock bottom end RB26 with a Greddy 1.2mm head gasket and Greddy drop in cams

Wow why u making so much power man- 450ish rwkw is it?? How much boost and no E85?

Sucrogen, we don't get E85 on pump over here

About 450kw at the hubs yeah, boost is on the graph 1.6bar to beef up the mid range and 1.4 bar top end. It's running E85

Awesome results mate. Hurry up and go to the drags

I considered cams

Hows it feel on the road?

[donut_kng]

What rear housing is on the 6262?

Maybe, depends if I can be stuffed. Cams should make a bit more power, if you do cams I'll do another pump

Only drove it about it 200m, gave it stick in 1st and 2nd, held on... Was good!

What rear housing is on the 6262?

T4 0.84 divided

Very nice power! Looks a bit laggier than a Gt3582r, which isn't really that bad news on a turbo that will make as much power as this if you tried pushing it :-)

We overlayed a few GT3582R graphs and they were similar response. Remember hub dyno makes things look lazier than a roller graph and the run was only started at 3000rpm so not much time to wind up the big girl. Could make big power with another pump though, would go close to 700 if we were crazy haha

The boost isn't falling over top end either, it's just we layed more boost into the mid range to beef up the torque. If we had held that boost through it would have run out of fuel (and probably make another 30-40hp)

sorry if ive missed it, wondering if that a stock bottem end?

[SiR_RB]

Yes stock rb26 bottom end

[Mitcho_7]

More boost and a set of dirty great cams Jez?

Yeah it's pretty clear it has plenty more flow in it - no question of that, for the lag it'll make way more than a GT3582R. I am most familiar with hub dynos, and the .82a/r T3 single scroll GT3582Rs tend to be all on by around 4300-4500rpm so barely any more lag considering the extra power but I'd have guessed it to be noticeable.

Compared with the T88 it's noticeable haha

[Frosty]

it looks so small in the engine bay....lol

[Anz32GTR]

hey everyone just wondering if anyone has a graph with a 64-66 on a rb26. . just wanna know proven figure without e85 just bp 98 pump.

thanks
